Abstract

A rotary knife (10) comprising, an annular blade (12) having a central axis (14), a blade supporting head assembly (16) supporting the blade for rotation about the axis, a manually grippable handle assembly (20) connected to the head assembly, and a flex shaft drive transmission (22) for driving the blade about the axis. The handle assembly comprises a core (150), a hand grip (152) surrounding the core, and a connector unit that secures the hand grip to the core. The core has a first end region (160) rigidly fixed with respect to the head assembly and a second end region (162) spaced from the head assembly. The core defines a drive transmission guiding channel leading toward the blade. The hand grip has a first end region (183) proximal the blade support assembly and a second end region (184) proximal the second core end region (162). The connector (154) detachably secures the hand grip in fixed relationship with the core. The connector engages the second end regions and is detachable for enabling hand grip removal and replacement.
